INSECT-EXTERMINATO R.

SPECIFICATION forming part of Letters Patent No. 429,345, dated June 3, 1890. Application tiled March 6, 1890. Serial No. 342.923. (No model.)

To all whom, it may concern:

Be it known that I, THEO GRAY, a citizen of the United States,`residing at Columbus, in the county of Franklin, State of Ohio, have invented certain new and useful Improvementsin Insect-Exterminators, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in insect-exterminators and it has for its object, among others, to provide a simple, cheap, and eiiicient device of this character, composed of few parts, that .shall be perfectly safe in use, provision being made against explosion, the two partsone the chemical-holder and the other the heater-hinged together with a suitable catch to hold them together.

Other objects and advantages of the invention will hereinafter appear, and the novel Vfeatures thereof will be specifically defined by the appended claims.

The novelty resides in the peculiarities of construction, as will be more fully hereinafter described, shown in the drawings, and then particularly pointed out in the claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which- Figure l is a side elevation of my improved insect-exterinihator. Fig. 2 is a vertical section through the same.

Like letters of reference indicate like parts in both figures of the drawings. y

Referring now to the details of the drawings by letter, A designates the heater portion, which is formed of any suitable metal and of any desired shape and size. It is provided with an alcohol-receptacle A', provided with a removable screw-threaded cap A2, by means of which the i'luid may be introduced.

`This cap has a wick-tube a passing therethrough, which tube also passes through an air-chamber h, the exterior threads of which the cap engages, as shown in Fig. 2. This air-chamber prevents heating of the fluid within the reservoir. The top of the reser- Voir has an opening for the passage 0f the wick-tube, the metal around said opening being upturned, as shown in Fig. 2, to provide a sort of nipple to guide the tube and provide a better hold therefor. Suitable openings a for the ingress o f air to aid combustion are provided in the bodyot the heater portion, as shown, preferably at a point about on a level with the highest point of the top of the reservoir. Vent-openings b should also be provided for the escape of gas and to prevent injury to the bottom of the chemicalholder,"soon to be described.

B is the upper portion, which constitutes the chemical-receptacle. It has a convex bottom, as shown in Fig. 2. The adjacent edges of the two portionsvr are beaded or rounded, as shown in Fig. 2, which allows them to turn on each other when desired, as when the upper partis thrown back to provide access to the burner. The portion B is hinged to the portion Aby means of av suitable hinge O, formed 'preferably ,of wire, one portion secured to the lower portion A and bent outward at the upper end to conform to the curve of the rim, as shown in Fig. 2, and the other portion connected therewith in any suitable manner to form a hinge that will allow of easy movement of the parts. Opposite the hinge there is provided a catch to lock the parts together. It consistsot' a spring-arm D, attached at its lower end to the lower 'portion A within its free end, bent to engage over the rim on the bottom edge of the upper portion B, and formed with suitable eye or thumb piece.

E is akeeper on the lower portion A, through which the free end of the spring-armA passes and is guided, the said keeper being secured to thelower portion in any convenient manner.

F is a handle to the upper portion B, by which it may be handled and carried from place to place when desired.

G is a removable cap to the chemical-receptacle, said cap being formed with a nipple g to receive one end of a flexible pipe H, the said nipple being inclined from a perpendicular, as shown, so as tohold the pipe from contact with the metal portions of the device, as will be readily understood. The other end of this pipe is provided with a metallic dis'- charge-nozzle I, which is seated in a prefer- IOO ably Wooden handle J, which prevents the hand from becoming heated during the use of the device. This handle is made easily removable to allow of the nozzle being inserted in cracks or crevices When desired.

The manner of use will be apparent. Alcohol or any other desirable fluid is placed in the lamp and Water and chemicals in the upper receptacle. I employ aqua-ammonia and sometimes carbolic acid, and sometimes may dispense with the use of either, employing steam alone, but prefer to use either the aqua-ammonia or the carbolic acid, as I have found from experience that some insects can be killed much quicker when Veither the one or the other is used. The lamp being lighted, the heat creates steam Within the chemicalreceptacle, which gives pressure, so that it willbe forced into and penetrate cracks or crevices into which the discharge end of the nozzle may be introduced. The flexible pipe, besides serving to convey `the vapor to the cracks and crevices, serves also as a safetyvalve and prevents explosions.

The device is simple, cheap, durable, and in practice has proved to be very efficientior the purpose for which it is intended.

l. The combination, with the heater portion having reservoir, air-openin gs, and vents, of the receptacle arranged above the heater portion and hinged thereto and supported directly thereon and provided Withvapor-conveying tube, substantially as described.

2. The combination, with the chemical receptacle having vapor-conveying tube, of the heater portion formed with fluid-receptacle, having an air-chamber on the top of the said receptacle, and a removable cap surrounding said air-chamber and carrying a Wick-tube passed therethrough, substantially as specied.

3. The combination, with the heater portion having duid-reservoir, of the chemicalreceptacle hinged to and restingdirectlyupou the heater portion, and a removable cap therefor provided with an inclined nipple and a iiexible tube connected with said nipple, substantially as speciiied.

4. The combination, with the heater portion provided with Huid-reservoir and `the chemicalreceptacle hinged to and supported directly upon the same, of the cap to the chemical-receptacle, the flexible tube connected with said nipple, and the dischargenozzle on said tube provided with a removable surrounding handle, substantially as specilied.

In testimony whereof I afiix m y si gnature in presence of two witnesses. THEO GRAY. Witnesses:
